Bitmine Nears 5% Ethereum Ownership Target as Staking Rewards Add Up

Bitmine continues to accumulate Ethereum even as staking income could soon do much of the work in pushing the firm toward its stated goal of owning 5% of the network. The Nasdaq-listed treasury company said it bought 53,501 ETH in the week through Aug. 30, lifting total holdings to 5.9 million ETH. It also reported that more than 5.06 million ETH were staked, earning an annualized seven-day yield of 2.67%. Additional buying may have followed. On Sept. 1, blockchain analytics firm Lookonchain reported that wallets it attributes to Bitmine appeared to acquire another 51,000 ETH, valued at about $126 million, from FalconX and BitGo. Bitmine has not formally confirmed that transaction in its latest corporate disclosure. If the attribution is accurate and the transfer reflects a net new purchase, Bitmine's holdings would rise to roughly 5.95 million ETH. Staking could close the remaining gap Using Bitmine's own reference point of 120.7 million ETH in circulation, a 5% stake implies roughly 6.035 million ETH. Against the company's disclosed 5.9 million ETH balance, that leaves a shortfall of about 134,000 ETH. With 5,067,309 ETH staked as of Aug. 30, keeping the staking balance and the stated yield constant would generate roughly 135,000 ETH in rewards over a modeled year. Under that snapshot, Bitmine would need to retain nearly 99% of those rewards to exceed 5% within a year, assuming the network's ETH supply does not change. If the reported Sept. 1 purchase were added, the math shifts. An incremental 51,000 ETH would shrink the gap to about 83,000 ETH under the same 120.7 million supply benchmark, meaning roughly 61% of one year's modeled staking rewards could be enough to bridge it under fixed-yield, flat-supply assumptions. Supply growth makes the target a moving number Ethereum's supply is not static, and a larger denominator raises the amount Bitmine must hold to maintain a 5% share. Etherscan showed roughly 122.02 million ETH outstanding on Sept. 5. Holding Bitmine's Aug. 30 balance constant against that figure implies an illustrative ownership share of about 4.84%, widening the gap to nearly 200,000 ETH. Over a two-year horizon, even modest supply changes materially alter the retention requirement. Based on the disclosed Aug. 30 holdings and staking balance: Assumed annual net ETH supply change | Reward retention needed to reach 5% after two years -0.5% | About 51.4% 0% | About 73.9% +0.5% | About 96.5% +1.0% | About 119.2%; not achievable under these assumptions. A lower staking yield tightens the constraint. At a 2% yield, modeled annual rewards fall to roughly 101,000 ETH, pushing the flat-supply, two-year retention threshold to almost 99%. The key variable: how much ETH Bitmine keeps As the company's position grows, reaching 5% increasingly looks like a capital-allocation question rather than a pure buying program. Bitmine has said it periodically converts ETH-denominated staking rewards into U.S. dollars and has not committed to a fixed retention rate. Retaining more rewards increases ETH holdings without additional market purchases; converting rewards to cash can fund operations and shareholder commitments. Bitmine's management agreement with Ethereum Tower includes reward-linked compensation plus infrastructure and custody costs. The company has also declared 17 cash dividends on its BMNP preferred stock, with scheduled payments running through late December. In its quarterly filing, Bitmine warned that changes in ETH prices and staking yields could affect its ability to fund operations and preferred dividends. Because staking rewards are paid in ETH, meeting cash obligations can require selling tokens that would otherwise move the treasury closer to 5%. For investors, the most important disclosure may shift from how much ETH Bitmine buys to how much of the ETH it earns the company ultimately retains.
